Anisotropic monoclinic zirconia particles (aspect ratio of 4–10) have been prepared upon hydrothermal processing of 1,12‐diaminododecane (DADD)‐hydrous zirconia gels at pH of 14 and at 230°C for 3 days. A biphasic growth model comprising melted DADD and the water/ethanol mixture is proposed to account for the generation of rod‐like morphology.
